Most people laugh when they first hear about the paid to poop side hustle, but it’s no myth — it’s a real, medically-backed opportunity to earn money while helping save lives. In this guide from Side Hustles Central, you’ll learn how stool donor programs work, how much you can earn, and whether you qualify. If you’ve got a healthy gut, this could be the easiest money you’ve ever made.
What Does ‘Getting Paid to Poop’ Actually Mean?
I remember the first time I heard someone say they get paid to poop — I thought it was a joke.
But it turns out, it’s one of the weirdest and most legit side hustles I’ve ever stumbled across. Known officially as being a stool donor, this opportunity falls under what some call the paid to poop side hustle, and it’s exactly what it sounds like — donating your stool for money.

Here’s how it works: you sign up with a stool donor program — usually through a stool bank, a medical research lab, or a fecal microbiota transplant (FMT) clinic. These organizations collect healthy human stool to treat patients with gut health issues, especially Clostridioides difficile (C. diff) infections. The science behind it is actually fascinating. Your gut bacteria — aka your microbiome — could help save lives.
Once accepted (and it’s a pretty strict screening process), you’ll be asked to donate your stool regularly. You typically have to be in excellent health, have a consistent schedule, and live near a donation facility. Each donation can earn you anywhere from $25 to over $500 per week, depending on the program. That’s not bad for something you do naturally every day.
Stool donation payment varies, but if you’re consistent and meet the requirements, you can turn this into a solid stream of side income. I’ll be honest — it’s one of the most unique gigs I’ve tried, and definitely the strangest way I’ve ever earned cash.
Why Stool Donations Matter: The Science Behind It
Before I got into the whole get paid to poop scene, I honestly had no idea my poop could help anyone — let alone save lives.
It all comes down to the gut microbiome — that community of trillions of bacteria living in your intestines. When it’s healthy, it helps regulate everything from digestion to immunity. But when it gets thrown off, bad things happen. And that’s where stool donor programs step in.
Researchers discovered that people suffering from severe gut infections, like C. difficile, often have a destroyed microbiome. These patients can’t recover with antibiotics alone — they need a full reset. That’s where fecal microbiota transplants (FMT) come in. Doctors take healthy stool from a screened donor and transplant it into the patient’s gut, either via capsule, colonoscopy, or enema. It sounds gross, but it’s incredibly effective.
Honestly, I was stunned to learn how serious this is. One of the nurses told me about a patient who had been hospitalized multiple times, almost given up, and after one successful FMT, they walked out a different person. That hit me.
Here’s why this matters:
- C. diff patients are the main beneficiaries, but FMT is also being explored for conditions like IBS, Crohn’s, and even depression.
- Stool donors help restore balance in someone else’s gut, potentially curing them when nothing else worked.
- Your microbiome could literally be medicine for someone else.
So when people joke about the paid-to-poop side hustle, I remind them it’s more than just the money (though the stool donation payment is nice). It’s about being part of a breakthrough in medical science that’s still unfolding — and yeah, earning some extra cash along the way.

How Much Can You Earn as a Stool Donor?
If you’re wondering how much you can actually get paid to poop, I’ve been there. I had a lot of questions before I jumped into this unusual world. Let me tell you — the money can be surprisingly good, but it varies depending on where you donate and how often.
Some of the top stool donor programs offer consistent payments that stack up quickly. For example, one clinic I applied to in Boston offered $40 per donation, up to five times a week. That’s $200 a week, or roughly $800 a month just for doing something I’d be doing anyway. Other programs like HumanMicrobes have gone viral for offering up to $500 per sample to rare “super donors” with exceptional gut microbiomes.
Here are the main factors that influence your stool donation payment:
- Location: Urban areas with active FMT clinics or research centers tend to pay more.
- Health profile: The healthier and rarer your microbiome, the higher the value.
- Donation frequency: The more regular you are, the more money you can make.
- Program type: Academic research labs may pay less than commercial stool banks.
To give you a clearer picture, here’s a quick comparison of popular programs and what they pay:
| Program | Location | Payment per Donation | Max Weekly Earnings |
|---|---|---|---|
| OpenBiome | Boston, MA | $40 | $200 |
| HumanMicrobes | Remote (selective) | Up to $500 | Varies |
| Seres Therapeutics | Cambridge, MA | $50 | $250 |
The paid to poop side hustle might not make you rich overnight, but if you’re a good fit and live near the right facility, it can absolutely be a solid stream of passive income — with a strange but meaningful twist.
Best Paying Stool Donation Programs in the US
If you’re serious about the paid-to-poop side hustle, you need to know where to go. Not all stool donor programs are created equal. Some offer higher payouts, more flexibility, or even remote options. After diving deep into this world and applying to several programs myself, these are the three that stood out as the best in the U.S., for both stool donation payment and overall experience.
1. Human Microbes
By far the most talked-about program in the get paid to poop community, Human Microbes is known for its generous payouts — up to $500 per stool donation for select donors. The catch? They’re extremely picky. Less than 1% of applicants are accepted.
- Location: Remote (they accept shipments from anywhere in the U.S. if you’re approved)
- Requirements: Excellent health, healthy BMI, no antibiotic use in the past 6 months, a great diet
- How to Apply: Fill out their in-depth screening form at HumanMicrobes.org. Be prepared for follow-ups and stool testing.
This program is ideal if you have a clean bill of health and are willing to go through a rigorous process for a big payoff.
2. GoodNature (Rebyota by Seres Therapeutics)
GoodNature, a program by Seres Therapeutics, is another major player. They’re behind Rebyota, the first FDA-approved microbiome therapy for C. diff treatment. They pay around $50 per donation and up to $1,500 per month for consistent donors.
- Location: Cambridge, MA (and select drop-off locations)
- Requirements: 18–50 years old, healthy weight, no GI disorders, regular bowel movements
- How to Apply: Visit GoodNatureProgram.com and fill out the eligibility form. If pre-approved, you’ll do a stool test and clinical screening.
They’re great for people living near their labs, and the payment is reliable. Plus, you’re directly contributing to a life-saving treatment.
3. OpenBiome
OpenBiome is a non-profit stool bank that supplies material to hospitals and research centers. They were pioneers in the FMT space and offer about $40 per donation. You can earn up to $250 a week if you donate frequently.
- Location: Boston, MA (in-person donations only)
- Requirements: Excellent health, daily availability, and live nearby
- How to Apply: Apply to OpenBiome.org. If selected, you’ll undergo a health screening and stool testing.
This one’s best for locals — they want you to donate frequently and in person. But if you’re nearby, it’s a reliable source of stool donation payment.
Each of these programs offers a unique path into the world of getting paid to poop. Whether you’re in it for the money, the science, or both, choose the one that fits your lifestyle and location.

Eligibility Criteria: Are You a Good Candidate?
Before you jump into the get paid to poop lifestyle, you’ve got to ask the big question: Am I even eligible? Turns out, being a stool donor isn’t as easy as showing up with a sample. These programs take the screening process seriously — and for good reason.
The first hurdle is a detailed health questionnaire. All reputable stool donor programs will grill you about your medical history, recent illnesses, medications, travel habits, and even your daily routine. Then comes the real test — stool, blood, and sometimes urine samples to screen for infections and imbalances. They want to make sure your gut microbiome is not only healthy but also safe for transplant into vulnerable patients.
Here are the typical stool donation payment eligibility criteria:
- Age: Most programs look for donors aged between 18 and 50.
- BMI: A healthy Body Mass Index (usually between 18.5 and 30) is required.
- Lifestyle: No smoking, minimal alcohol, and a clean diet rich in whole foods and fiber.
- Medication: No recent antibiotic use (typically within the last 6 months).
- Travel: Avoidance of high-risk travel areas (due to risk of parasites or bacterial exposure).
If you’ve had any chronic GI issues, autoimmune diseases, or serious infections, you might be disqualified. Same if you’ve recently taken prescription drugs that affect the gut.
So yeah — the paid to poop side hustle is real, but it’s not for everyone. If you check all the boxes, though, you might just have gold in your gut.
Step-by-Step Guide to Becoming a Paid Stool Donor
So, you’re ready to get paid to poop — but how do you actually get started? I’ll walk you through the entire process based on my own experience and what I learned applying to different stool donor programs.
1. Start with the Application
Most programs begin with an online form where you’ll answer questions about your health, diet, lifestyle, and bowel habits. Be honest — they’re looking for people with regular, healthy digestion and zero chronic issues.
2. Medical Pre-Screening
If you pass the first round, you’ll usually go through a phone or email consultation. After that, they’ll schedule lab testing. This includes:
- Blood tests to rule out infectious diseases
- Stool tests to analyze microbiome quality
- Sometimes, urine tests or vital signs checks
3. Submit a Sample
If your initial screening looks good, they’ll ask for a stool sample. Some programs require you to drop it off within a short time window (1–2 hours after passage), while others — like Human Microbes — may let you freeze and ship it if approved.
4. Final Approval
Once your sample is analyzed and you’re cleared, you’ll officially become a donor. This is where the stool donation payment begins — and the paid-to-poop side hustle becomes real.
5. Ongoing Commitment
Programs expect consistency. That could mean showing up 3–5 times a week or sending regular shipments. You’ll also have periodic re-testing to make sure your gut health is still optimal.
It’s not a one-and-done deal. You become part of a medical ecosystem, helping people with life-threatening conditions. And yeah — you get paid for it. Not bad for something that’s already part of your daily routine, right?
Tips to Maximize Your Earnings
Once you’ve joined a stool donor program, the next step is making the most of the opportunity. If you want to really get paid to poop consistently — and make it a real paid-to-poop side hustle — here are some tips that worked for me.
1. Stay Consistently Eligible
The biggest mistake donors make is slipping on eligibility. One antibiotic, one stomach bug, and boom — you’re out. To stay qualified:
- Stick to a clean, gut-friendly diet (fiber, fermented foods, low sugar)
- Avoid antibiotics unless necessary
- Minimize travel to regions flagged for disease exposure
2. Optimize Your Gut Health
Gut health is the foundation of your stool donation payment potential. Probiotics and prebiotics are your friends. Think: yogurt, kefir, bananas, oats, and leafy greens. Drink plenty of water, stay active, and reduce stress — your microbiome feels everything.
3. Look for Multiple Opportunities
Don’t rely on just one clinic. Join donor waitlists and subscribe to research trial boards. Sites like ClinicalTrials.gov or Reddit threads on stool donation sometimes post about new studies looking for participants.
The more you commit to your health and stay in the loop, the more you earn — simple as that. And honestly? It feels good knowing your side hustle helps save lives.
Alternatives to Stool Donation That Pay Well
If the idea of being part of a stool donor program isn’t for you — or you don’t qualify — don’t worry. There are other ways to earn money from your body (or even your pet’s poop) that might be more up your alley. Here are some legit side hustles that can match or even beat stool donation payment.
1. Donating Plasma
This is one of the most common medical gigs. You can donate up to twice a week and earn between $30 to $70 per session. That’s up to $500/month. It helps patients with immune disorders, burns, and clotting issues — and it’s quick once you’re in the system.
2. Medical Research Studies
Universities and research hospitals pay participants to test new treatments or answer health-related questions. Some studies pay hundreds or even thousands, depending on time and commitment. Check ClinicalTrials.gov or local hospital websites.
3. Sperm or Egg Donation
For those who qualify, egg donation can earn women between $5,000 and $10,000 per cycle. Sperm donation typically pays around $75 per sample, but you’ll need to commit long-term and meet strict health criteria.
4. Pet Waste Cleanup Services
Yes, you can make money cleaning up after dogs. Services like DoodyCalls or local businesses hire people to scoop poop for pet owners. It’s low-skill, flexible, and oddly profitable — sometimes $20–$50 per yard.
So even if the paid-to-poop side hustle isn’t the right fit, your options are wide open. The human (and pet) body really is full of weird ways to earn.

Is It Worth It? Pros and Cons of the Poop Hustle
After diving into the get-paid-to-poop lifestyle, I’ve been asked the same question more times than I can count: “Is it actually worth it?” Honestly? It depends on your health, your location, and your comfort level with the whole idea.
Pros
- Decent income: With some stool donor programs, you can make up to $1,500 a month — not bad for something you do anyway.
- Helping others: Your stool could literally save a life, especially for patients with recurrent C. diff infections.
- Low time commitment: Some donations take under 30 minutes, including travel, and there’s no prep work like with plasma or blood donation.
Cons
- Strict eligibility: The screening process is intense, and even a small health hiccup can disqualify you.
- Privacy concerns: Not everyone’s comfortable discussing or sharing details about bowel habits.
- Limited locations: Unless you live near a clinic, you might have trouble finding a reliable program.
One donor told me, “It’s weird at first, but when I saw how it helped someone, I felt like I was doing something bigger than myself.” That stuck with me.
The paid-to-poop side hustle definitely isn’t for everyone. But if you’re healthy, nearby, and open-minded, it might just be the most impactful money you’ll ever make.
Conclusion
By now, you’ve seen that the get paid to poop opportunity is real — and not just a quirky internet myth. With reputable stool donor programs like Human Microbes, GoodNature, and OpenBiome offering legit payouts, this side hustle has gone from taboo to trending.
Sure, it’s not glamorous. But if you’re healthy, meet the requirements, and live near a clinic (or qualify for remote shipping), this could be one of the easiest ways to make money while literally doing what comes naturally. From $40 per donation to as much as $500 for rare “super donors,” the stool donation payment potential is surprisingly solid.
The paid-to-poop side hustle also carries a unique reward: helping people suffering from serious gut conditions like C. diff. It’s income with impact — something not many side gigs can claim.
If you’re curious, healthy, and meet the eligibility criteria, why not apply? Your gut could change someone’s life — and boost your income in the process.
Frequently Asked Questions
Can I really get paid just to poop?
Yes, you absolutely can get paid to poop. Legit stool donor programs partner with FMT clinics and research institutions to collect healthy stool for medical treatment. If you qualify, you can earn between $40 to $500 per donation, depending on the program. It’s weird — but it’s real.
How do I keep my stool “donation ready”?
The key is gut health. Eat a fiber-rich diet, stay hydrated, and avoid antibiotics or anything that could disrupt your microbiome. Some donors take probiotics, but whole foods like oats, bananas, kefir, and leafy greens are usually enough. Staying consistent is what keeps you eligible for stool donation payment long-term.
Can I do this if I have a health condition?
It depends on the condition. Most paid-to-poop side hustle programs screen out applicants with GI disorders, autoimmune conditions, recent surgeries, or chronic illnesses. Even common issues like IBS or eczema can be red flags. Always check the eligibility criteria for the specific program you’re applying to.
What if I live outside the US?
Most major programs — like OpenBiome and GoodNature — only operate within the United States. However, Human Microbes accepts remote donors from other countries if they meet the strict health requirements and can ship samples correctly. So while it’s harder, it’s not impossible to join a stool donor program from abroad.
Still got questions? The best way to learn is to apply and see if you qualify. Worst case, you walk away with more knowledge about your gut — best case, you help someone and get paid for it.
What are the qualifications to get paid to poop?
To qualify for a stool donor program, you usually need to be between 18 and 50 years old, have a healthy BMI, have no chronic medical conditions, and have no recent antibiotic use. Programs also look for individuals with regular, healthy bowel movements and excellent gut microbiome diversity. You’ll go through medical screenings and lab testing before you can get paid to poop.
What is the 3 poop rule?
The “3 poop rule” isn’t an official medical term, but it’s often used informally to refer to what’s considered a normal range for bowel movements — anywhere from three times per week to three times per day. For stool donor programs, going once per day is usually ideal, as consistency matters for sample quality and donation timing.
What is the 7-second poop rule?
The “7-second poop rule” is more of a social media myth or humorous concept than a scientific guideline. It implies that a healthy bowel movement should take no more than 7 seconds to pass. In reality, while fast and effortless poops can be a sign of good gut health, there’s no strict time limit. What matters more is consistency, shape, and ease — especially if you’re aiming to earn a stool donation payment.
Is poop 70% water?
Yes, approximately 70% to 75% of human stool is made up of water. The rest is a mix of undigested food, bacteria, fiber, cells, and mucus. This water content plays a role in determining stool texture — too much or too little can affect eligibility in paid-to-poop side hustle programs that require healthy, well-formed samples.
